What would the geological effects be on Venus if it was suddenly

Unfortunately comparative planetography hasn't reached the point where we can reliably say. There's no shortage of unanswered questions about our own planet either.

Erosion would change completely from wind/acid to wind and water erosion.

CO2 cycle would depend on if Venus also has tectonics, otherwise all CO2 will be bound into minerals over time.

Venus has no tectonic activity, as far as we know. This, combined with its closer proximity to the Sun are some of the reasons it's a hothouse. It also has a much lower rotation rate than Earth, meaning it likely doesn't have a liquid outer core or a magnetic field to keep out harmful solar radiation.

Honestly, Venus would be nearly impossible to terraform, compared to planets like Mars that we can probably inhabit, although adapting to any other planet's gravity will be cumbersome. Mars doesn't have a magnetic field either, so either way you are fucked for the long haul as solar wind strips away the atmosphere.

You also have to take into account Venus's slow rotation rate. even If you were to replace venus's atmosphere with an atmosphere similar to earths. It still behave differently due to slow rotation and all the other things that come out of that.

Did you guys even read my post? I addressed the rotation speed and the orbit. Next time read the whole post instead or skimming it or auto responding.

Wouldn't the change in temperature on the surface provoke plate tectonics? The reason we have it is because of the temperature difference between the surface and the interior of our planet. Would the same not happen on Venus?

Venus and Earth Would most likely destroy each other due to their Close proximity
